We have a Garmin chart plotter and an I Pad on board with a GPS app. Which unit updates faster? We use GPS on some of our predicted log contests and lag time is a factor.
So 0.1Hz gives me a refresh rate of once every second. At an average boat speed of 8.5 knots that should be adequate for a predicted log contest. Don't know if I can decrease the lag time with my old Garmin 172C. I'll find out this weekend.
